Description of key information
In a 21-d GLP study performed according to OECD 211 the EC50 on the most sensitive parameter, which was immobilisation, was determined to 1 mg/L. The EC50 for reproduction was 1.4 mg/L and the NOEC was determined to 0.74 a.i mg/L based on nominal concentrations.
Key value for chemical safety assessment

- 0.74 mg/L
Additional information
The results are read across from the a test performed with a structurally similar compound Benzenesulfonic acid, 4-C10-13-sec-alkyl derivs., compds. with N-[3-(dimethylamino)propyl]-2-methyl-2-propenamide (1:1), (MAPDA-ABS salt). Read across to MAPTA-ABS salt is based both on the chemical similarity and the results of the short term study performed with Daphnia and the algae study. Both of these studies indicate that the two substances in the category have toxicity in the same range.
